“…No other experimental method provides a comparable dynamics resolution. In transition metal oxides and their mixed systems, the electrical conduction has been studied extensively due to its incompletely filled 3d shell (Alonso-Domínguez et al, 2016;Baghizadeh et al, 2015;Biju & Khadar, 2003;Boukhachem et al, 2016;Dridi et al, 2015;Khumpaitool & Khemprasit, 2014;Rouahi et al, 2016;Wypych et al, 2014). Among these metal oxides family, hausmannite Mn 3 O 4 has attracted much interest due to its typical intrinsic p-type conductivity (Bose & Biju, 2015aLarbi et al, 2014;Ulutas et al, 2016).…”

In this work further optical and electrical investigations of pure and Zr doped Mn 3 O 4 (from 0 up to 20 at.%) thin films as a function of frequency. First, the refractive index, the extinction coefficient and the dielectric constants in terms of Zr content are reached from transmittance and reflectance data. The dispersion of the refractive index is discussed by means of Cauchy model and Wemple and DiDomenico single oscillator models. By exploiting these results, it was possible to estimate the plasma pulse ω p , the relaxation time τ and the dielectric constant ε ∞ . Second, we have performed original ac and dc conductivity studies inspired from Jonscher model and Arrhenius law. These studies helped establishing significant correlation between temperature, activation energy and Zr content. From the spectroscopy impedance analysis, we investigated the frequency relaxation phenomenon and hopping mechanisms of such thin films. Moreover, a special emphasis has been putted on the effect of the oxidation in air of hausmannite thin films to form Mn 2 O 3 ones at 350°C. This intrigue phenomenon which occurred at such temperature is discussed along with this electrical study. Finally, all results have been discussed in terms of the thermal activation energies which were determined with two methods for both undoped and Zr doped Mn 3 O 4 thin films in two temperature ranges.
